Introduction to Retort Bags
Retort bags, also known as retort pouches, are flexible packages designed to withstand the high - temperature and high - pressure conditions of the retort sterilization process. This process involves heating the filled bags to a specific temperature (usually between 110 - 135°C) for a certain period to kill microorganisms and enzymes, thereby extending the shelf - life of the food or other products inside. Retort bags are widely used in the food industry for packaging ready - to - eat meals, soups, sauces, pet foods, and more. They offer several advantages over traditional packaging methods such as cans, including lighter weight, reduced storage space, faster heating, and better preservation of nutrients and flavors.
